An internal Lamborghini presentation has found its way onto the web, revealing details of the new Murcielago LP650-4 Roadster.

The mysterious machinations of the Internet have placed internal Lamborghini documents on the LamboCars forum, which is of course the most natural place for them to be. That means that we get a sneak peek at factory pictures of the upcoming Lamborghini Murcielago LP650-4 Roadster. This limited-edition supercar will see a run of just fifty cars and is scheduled to debut shortly.

The photos, which appear to be a PowerPoint presentation, show the interior and exterior of the LP650-4 Roadster in production trim with notes. Read it aloud to yourself, and it might be just like being at the press conference.

As the name suggests, the LP650-4 Roadster gets the same 6.5 liter, 650-horsepower V12 as the Reventon, 18 horsepower more than the LP640-4. Special gray trim with orange details and black wheels set the special edition apart. Lambo's e-gear transmission, a navigation system and back-up camera will also be available. Lamborghini reports a 3.4 second 0-60 run, and pricing will be around $400,000 when the Murcielago LP650-4 Roadster goes on sale. We doubt it'll be around for long.
